 The figure shows the section of a gravity dam (non-overflow portion) built of concrete. Calculate (neglecting earthquake effects). (13 mark)       Dec 2016

i. The maximum vertical stresses at the toe and heel of the dam

ii. The major principal stresses at the toe of the dam

iii. Intensity of shear stress on a horizontal plane near the toe

Assume the unit weight of concrete = 23.5 kN/m2.

Allowable compressive stress in concrete = 2500 kN/m².

Allowable shear stress in concrete = 420 kN/m².

Assume that reservoir is full of water up to M.W.L.
